Rolex Datejust 36 36 mm 126234BLSJ Steel/White Gold Blue Rolex Datejust 36 36 mm 126234BLSJ Steel/White…

The Rolex Datejust is one of the most enduring icons in watchmaking history, having introduced the instantaneously jumping date display at 3 o'clock to the wrist-watch world in 1945. Decades of continuous refinement have brought the line to its current generation, represented by references in the 126200 family, and the 126234BLSJ sits at an especially desirable position within that family by combining two prestigious materials with one of the most expressive dial choices available.

The 36mm Oyster case of the Datejust 126234BLSJ is constructed from Rolex's proprietary Oystersteel, an alloy in the 904L family prized for its exceptional resistance to corrosion and its ability to take and hold a high polish over years of daily wear. The integration of 18k white gold — appearing on the fluted bezel — elevates the watch from a sport-adjacent steel piece to a genuinely dressy proposition, and Rolex's precision machining ensures the two materials meet seamlessly on the wrist.

The blue dial of this reference is a defining element. Blue has grown into one of the signature Datejust dial colours of the modern era, beloved by collectors for the way it shifts in character from deep navy in low light to a bright, lively azure in full sun. Set against the bright white-gold fluted bezel, the contrast is immediately striking and unmistakably Rolex in its poise and restraint.

The watch is presented on Rolex's five-piece Jubilee bracelet, originally introduced alongside the very first Datejust in 1945 and refined continuously ever since. The Jubilee's characteristic centre-link pattern lends the 126234BLSJ a supple, dressy drape on the wrist that distinguishes it from sport-oriented Oyster-bracelet variants, making it an ideal companion for both formal occasions and smart-casual daily wear. The Oysterclasp secures the bracelet with ease while permitting fine adjustment for comfort.
